ACC and fuel pump prime Issue
ACC and fuel pump prime Issue
s13 Redtop 1601 Aem EmsSo I recently got everything hooked up finally. The fuel pump primes when the car is on the on position, just as it should. With the key in the ACC position, second turn of the key, I push in the brake pedal the pump primes. I hit the hazards, the pump primes. Use the turn signal, pump primes. Im guessing that fuel pump wiring got crossed with ACC line somewhere, but not sure. The thing is I havent touched my fuel pump in like 2 years. During my build I didnt touch the fuel pump at all.The only wiring i touched was having to hook up gauges and hooking up the EMS. I did do repinning on the EMS for MAP and IAT sensors. I saw that on the EMS there is a Fuel pump pin but never had to touch it and never did. Anyone run into this problem??

Ok so i hooked up my stock ECU and now its all acting normal. So it has to do with the EMS. Any inputs would be great.
Re: ACC and fuel pump prime Issue (sl87)
Ok so Ive tried unplugging any sensor i could find and see if the pump will prime if i connect one sensor at a time and hit any Accessory (brake, hazard, turn signal ect.) The culprit is the CAS (cam angle sensor).
When key is on position:I plug the sensor in, the pump primes.I unplug the sensor, the pump primes.I plug the sensor in, and hit Accessory pump primesI unplug the sensor, and hit Accessory pump DOES NOT prime.
IM SO DAMN CONFUSED!!!I did all the calibrations and uploaded the base maps. My sister took the laptop right when i needed it. So i havent had the chance to check anything in the AEM program that may cause this problem. Im going to check the program tommarow and see if there is any setting that i screwed with.
INFO:I am running my MAP sensor off my MAF wiring.I am running an AIT sensor.I repinned them to the correct locations (MAP is pin 35, AIT is pin 26)I currently just relocated those pins back to their stock locations and see if the problem persisted (It did)When I plug my stock ECU in, there is no problem at all. Even with MAP AND AIT sensors pinned in correct locations and also pinned back to stock.With MAP and AIT sensors pinned to correct locations (AEM pinout) I have started the car and it did idle.
Please help me out. YES i did talk to AEM technician and he helped me out finding the weird CAS situation (process of elimination of sensors) but couldn't pin the exact problem. All he said was to check my wiring (Which i didnt touch during my build except for MAP and AIT wiring)
